Bell hydraulic excavators – the HD1023 Mark 3 and HD820 Mark 3, 110.1 to 125.1 kW, 19,700 to 23,570 kg operating weight, 6D34-TLE engine
This page gathers the hydraulic excavators HD1023 Mark 3 and HD820 Mark 3 from Bell, the South African construction-equipment maker based in Richards Bay. Bell Equipment was founded in 1954 and remains family-owned to this day. The "HD" designation marks the hydraulic-excavator range, the number the approximate weight class, and the "Mark 3" suffix the third generation of that range.

The register lists here 2 versions at 110.1 to 125.1 kW from six-cylinder engines of the 6D34-TLE type, with operating weights from 19,700 to 23,570 kg.
Hydraulic excavators of this weight class are the workhorses of earthmoving and civil-engineering sites; Bell positions its excavator range alongside its core articulated-dump-truck business chiefly in southern Africa and through international dealers, where rugged construction and straightforward maintenance under demanding conditions come first. Rugged construction and straightforward mechanical design make repairs easier away from well-developed workshop infrastructure, an important purchasing argument in many African countries of operation.
On used examples, operating hours and the condition of the six-cylinder engine, undercarriage wear and track tension, the tightness of the hydraulic cylinders on the boom, arm and bucket, and the condition of the cab mounting all matter; spare parts run through the Bell dealer network.
